fast-export can fail because of some pruned-reference when importing a
mark file.
The problem happens in the following scenario:
$ git fast-export --export-marks=MARKS master
(rewrite master)
$ git prune
$ git fast-export --import-marks=MARKS master
This might fail if some references have been removed by prune
because some marks will refer to non-existing commits.
Let's warn when we have a mark for a commit we don't know.
Also, increment the last_idnum before, so we don't override
the mark.
